The Information Management System Of Urban Rail Transit Network

Recently,along with the rapid development of economic and urbanization,the problem of urban traffic congestion is becoming an overall situation that affects normal urban function exertion and urban continually development.Urban rail transit is an way to alleviate this problem above.Traffic information should be an important information which is showed to passengers,such as a message that about congestion.It is convenient to use travel modes and select travel route.Therefore,we should develop an information system for rail transit network which is passengers based.It including network basic facts and traffic information.In addition,the system can use the existing data to evaluate the network structure of the whole rail network.In general,we can use information management system to collect and store the data and data of urban rail transit network,and gradually form an expert system to guide the construction and scientific research.Based on the principle of "developing the vector graphics system and database management system,then establishing the connection between the vector graphics system and database management system,and developing kinds of query,spatial analysis and network analysis system",the system is developed.First of all,to complete the construction of the core part of the vector graphics system of rail transit network model,GIS is applied;secondly,after the researching and analyzing the network data structure,the development of the network attribute database management system is completed;finally,this paper introduces and analyzes the method to analyze the best path in the system.Through the research of these parts,we have basically completed the development of the system.Through the system development,the system has realized the function of the information management and the shortest path inquiry of the rail network.As for the system structure of network analysis function,transfering system of rail network topology data elements with the theory of complex network,the network structure and network connectivity reliability analysis of Beijing city rail transit network can be made using Matlab software.Meanwhile,according to the analysis results,a simple safety classification is carried out for Beijing rail transit station.Through the research of all these parts,the system has basically realized the function of the information management and network structure analysis of the rail network.
